Answer to Question #49556 in Atomic and Nuclear Physics for askandar

Question

what are types of absorption coefficient?
what are the parameters which absorption coefficient dependence on?
Can make alpha, beta and gamma rays energies approaching to zero?

Answer 1

1. Molar absorptivity,also called "molar extinction coefficient", which is the absorption
coefficient divided by molarity.
The mass attenuation coefficient, also called"mass extinction coefficient", which is the absorption coefficient
divided by density .

2. The absorption coefficient depends onthe material and also on the wavelength of light which is being absorbed.
