what type of decay does am-241 undergo to become np-237?

when a decay involves a loss of 4 from mass number and 2 from atom number , the decay characterizes an alpha decay, and the decay equation can be written as follows

²⁴¹₉₅Am → ²³⁷₉₃Np +?  the only type of decay that will satisfy this equation is alpha decay. therefore the above equation will be

²⁴¹₉₅Am → ²³⁷₉₃Np + ⁴₂He.
