isomer shift वाक्य

For this reason it is highly recommended to provide the isomer shift values with respect to the source used, mentioning the details of source ( centre of gravity of the folded spectrum ), instead with respect to iron foil.
Isomer shift ( chemical shift, CS ) can be expressed using the formula below, where K is a nuclear constant, the difference between R e 2 and R g 2 is the effective nuclear charge radius difference between excited state and the ground state, and the difference between [ ? s 2 ( 0 ) ] a and [ ? s 2 ( 0 ) ] b is the electron density difference on the nucleus ( a = source, b = sample ).
