nuclear physics - favorable transitions during beta decay


I was reading wikipedia article on beta decay when I came to a section called "Fermi transition". So, the way I understood it is:


"During beta decays, nuclear transitions which involve net zero change in orbital angular momentum of the nucleus is highly favored."


Why is it so? Does it have to do anything with parity conservation? How do I account for such phenomenon?

classical mechanics - Moment of a force about a given axis (Torque) - Scalar or vectorial?

I am studying Statics and saw that: The moment of a force about a given axis (or Torque) is defined by the equation: $M_X = (\vec r \times \...
