Example #1

def test_sigma_a3():
    xs.xs_cache.clear()

    N = len(xs.xs_cache['E_n']) - 1

    E_g = [10.0, 20.0]
    phi_n = np.ones(N)

    sigma_a_g = xs.sigma_a("H1", E_g=E_g, phi_n=phi_n)

    expected = np.array([(2.97130000e-05 + 2.89150000e-05 + 2.67690000e-05)/3.0])

    assert_array_almost_equal(sigma_a_g, expected)
