    33.. This is a port of the original SasView html help file to ReSTructured text 
    44.. by S King, ISIS, during SasView CodeCamp-III in Feb 2015.

    1214The neutron scattering length density is defined as 
    1315 
    14 SLD = (b_c1 +b_c2+...+b_cn )/Vm 
     16SLD = (b_c1 + b_c2 + ... + b_cn) / Vm

    … …  
    2426------------------------------- 
    2527 
    26 To calculate scattering length densities enter a compound and a mass density  
    27 and click "Calculate". Entering a wavelength value is optional (a default  
    28 value of 6.0 Angstroms will be used). 
     28To calculate scattering length densities enter the empirical formula of a  
     29compound and its mass density and click "Calculate". 
    2930 
    30 * Formula strings consist of counts and atoms such as "CaCO3+6H2O". 
     31Entering a wavelength value is optional (a default value of 6.0 |Ang| will  
     32be used). 
    3133 
    32 * Groups can be separated by *'+'* or *space*, so "CaCO3 6H2O" works as well. 
     34*  Formula strings consist of atoms and the number of them, such as "CaCO3+6H2O". 
    3335 
    34 * Groups and be defined using parentheses, such as "CaCO3(H2O)6". 
     36*  Groups can be separated by *'+'* or *space*, so "CaCO3 6H2O" works as well. 
    3537 
    36 * Parentheses can be nested, such as "(CaCO3(H2O)6)1". 
     38*  Groups can be defined using parentheses, such as "CaCO3(H2O)6". 
    3739 
    38 * Isotopes are represented by their index, e.g., "CaCO[18]3+6H2O", H[1], or  
    39 H[2]. 
     40*  Parentheses can be nested, such as "(CaCO3(H2O)6)1". 
    4041 
    41 * Counts can be integer or decimal, e.g. "CaCO3+(3HO0.5)2". 
     42*  Isotopes are represented by their atomic number in *square brackets*, such  
     43   as "CaCO[18]3+6H2O", H[1], or H[2]. 
    4244 
    43 * Other compositions can be calculated as well, for example, for a 70-30  
    44 mixture of H2O/D2O write *H14O7+ D6O3* or more simply *H7D3O5* (i.e. this says  
    45 7 hydrogens, 3 deuteriums, and 5 oxygens) and the mass density calculated  
    46 based on the percentages of H and D. 
     45*  Numbers of atoms can be integer or decimal, such as "CaCO3+(3HO0.5)2". 
    4746 
    48 * Type *C[13]6 H[2]12 O[18]6* for C(13)6H(2)12O(18)6 (6 Carbon-13 atoms, 12  
    49 deuterium atoms, and 6 Oxygen-18 atoms) 
     47*  The SLD of mixtures can be calculated as well. For example, for a 70-30  
     48   mixture of H2O/D2O write "H14O7+D6O3" or more simply "H7D3O5" (i.e. this says 
     49   7 hydrogens, 3 deuteriums, and 5 oxygens) and enter a mass density calculated 
     50   on the percentages of H2O and D2O. 
     51 
     52*  Type "C[13]6 H[2]12 O[18]6" for C(13)6H(2)12O(18)6 (6 Carbon-13 atoms, 12  
     53   deuterium atoms, and 6 Oxygen-18 atoms).
