Abstract

Dynamical

R

-matrix methodology is used to determine the properties of the recently proposed

J^{π} = 2^{+}

,

Γ = 3.5

MeV,

E_{x} (res) = 40.2

MeV resonance in

{}^{4}{He}

. The calculations lead to a

J^{π} = 2^{+}

state with the following properties:

Γ = 6.0

MeV,

E_{x} (res) = 40.3

MeV, and

T = 0

. The calculations indicate the importance of

4 ℏ ω

components in the proper description of the 40 MeV state.
